Bosch Rexroth IndraDrive C Servo Drives (HCS01, HCS02, HCS03, HCS04 Series)

The Bosch Rexroth IndraDrive C servo drive line (Indramat HCS series) is a family of compact, high-performance drive controllers designed for single-axis industrial applications. These drives integrate both the inverter and power supply into one unit, eliminating the need for a separate power supply module​. IndraDrive C converters take in three-phase AC mains power and generate a DC bus, then output a controlled AC voltage of variable amplitude and frequency to drive servo motors​. This all-in-one design saves cabinet space and simplifies installation, making IndraDrive C units particularly suited for engineers and plant owners looking to streamline their motion control systems.

IndraDrive C Highlights: Bosch Rexroth’s IndraDrive C (HCS series) covers a broad range of power and performance needs, from the smaller IndraDrive Cs units up to heavy-duty HCS04 models. Key benefits and features include:

IndraDrive Cs: Rexroth HCS01 – Compact Servo Drive Series

The IndraDrive Cs series, designated as HCS01, covers the lower end of the power range in the IndraDrive family. These ultra-compact converters combine the power section and control section into a single unit​. This means a Rexroth HCS01 drive contains its own motion controller (if equipped with the appropriate firmware card) and power electronics together, simplifying installation for smaller systems. IndraDrive Cs drives offer features like Ethernet connectivity, a multi-encoder interface for various feedback devices, and integrated safety options built right in​. This makes them ideal for small-to-medium machines that demand high functionality in a tight space.

HCS01 Key Specs: IndraDrive Cs units operate from 0.15 kW to 14 kW continuous power range​, with maximum continuous currents from about 3.3 A up to 54 A depending on the model​. They accept 3× AC 110–500 V input, covering both low and high voltage supply networks​. All HCS01 drives use internal air cooling (integrated blower) and carry an IP20 protection rating for cabinet installation​. They are designed with a high overload capacity, allowing short bursts of higher torque output when needed for dynamic motion.

A representative model in this series is the HCS01.1E-W0018-A-03 compact converter (often written as HCS01 1E W0018 A 03 NNNN in part number form). This unit features a maximum output of 18 A and supports a mains connection of 3× AC 200–500 V ±10%​. Like other HCS01 variants, it has an infeeding power supply (able to regenerate braking energy to the DC bus or dissipate through resistors) and built-in braking chopper for handling motor deceleration. The IndraDrive Cs HCS01 drives are favored in applications such as packaging lines, textile machines, or any equipment where space is at a premium, but performance cannot be compromised.

IndraDrive C: Rexroth HCS02 – Medium Power Range Drives

Stepping up in size and capability, the IndraDrive C HCS02 series covers the middle range of power and current. Rexroth HCS02 drive controllers are compact converters with a similar integrated design, but they are paired with modular control option slots. Unlike the smaller HCS01 (which has the control built-in), the HCS02 drives have a slot for a plug-in control module, allowing different communications (Sercos, Profibus, EtherCAT, etc.) or performance levels to be chosen. This provides flexibility for engineers and system integrators to tailor the drive to their automation network and feedback requirements​. The IndraDrive HCS02 units still maintain a single-axis, all-in-one form factor with an internal power supply, making them a convenient choice for standalone axes that require a bit more power or customization.

HCS02 Key Specs: IndraDrive C HCS02 models typically span roughly 1.5 kW to 11 kW in continuous output power​. Their continuous output current ratings range from about 12 A up to 70 A, with the smaller units in this series handling ~12–28 A and the largest around 70 A​. Like the HCS01, the HCS02 drives accept wide-range 200–500 VAC three-phase input​and are cooled by internal fans. They also feature IP20 protection for cabinet mounting and include in feeding power capability. Notably, the HCS02 drives boast a high overload factor (up to ~2.5× rated current for short durations) to manage heavy acceleration or shock loads without tripping​.

Common HCS02 Models and Specifications:

• Rexroth HCS02.1E-W0012-A-03-NNNN – A 12 A compact converter suited for the lower end of the HCS02 range. It supports 200–500 V AC input and provides efficient power conversion for motors in roughly the 1.5–3 kW class​. This model is a great fit for light-to-medium duty axes that need more power than IndraDrive Cs can offer.
• Rexroth HCS02.1E-W0028-A-03-NNNN – A mid-range IndraDrive C unit rated at 28 A maximum output current and designed for motors in the few-kW up to ~7.5 kW range​. The HCS02.1E-W0028-A-03 integrates the same 200–500 V flexibility and is a popular choice for machine builders due to its balance of power and size.
• Rexroth HCS02.1E-W0070-A-03-NNNN  – The high end of the HCS02 lineup, this model delivers up to 70 A output, covering applications up to about 11 kW continuous output​. It retains the compact footprint while packing enough current for larger servo motors or actuators. Like all HCS02 variants, it includes internal braking circuitry and can handle regenerative energy efficiently.

All the above IndraDrive C HCS02 drives share the Indramat HCS series’ hallmark of reliability and ease of use. They feature diagnostic LEDs and optional control panels for quick status checks and parameter adjustments. Engineers appreciate that these drives can seamlessly integrate with Bosch Rexroth’s IndraDyn servo motors via plug-and-play parameter sets, as well as drive third-party motors with the multi-encoder interface. From an industrial perspective, the Bosch Rexroth HCS02 units offer a robust solution with minimal wiring and module count – crucial for business owners and plant owners aiming to reduce downtime and maintenance points on their production lines.

High-Power IndraDrive C: HCS03 and HCS04 Series

For high-power requirements, Bosch Rexroth provides the HCS03 and HCS04 series within the IndraDrive C family. These drives are built to handle the upper kW range and high continuous currents needed for large machinery. The Rexroth HCS03 converters generally cover approximately 22 kW up to 110 kW of continuous output power​, with maximum continuous currents from about 70 A to 350 A. Meanwhile, the HCS04 converters extend even further – into the hundreds of kW and up to ~1000 A in peak current capacity​. Despite their massive power, they still integrate the DC power supply and inverter in one unit, offering a single-axis solution for heavy-duty drive tasks (where traditionally a separate supply unit might have been required).

HCS03 Features: IndraDrive C HCS03 units include a control section slot like the HCS02, supporting various interfaces (Ethernet/IP, PROFIBUS, Sercos, etc.) and safety modules to connect with modern controllers​. These come standard with internal cooling and often an external heatsink or cold plate mounting option for better thermal management at high outputs. HCS03 drives have an overload capacity of around 150% for short periods​, sufficient for most heavy industrial cycles where peak loads are somewhat limited relative to the continuous demand. These drives find use in large printing presses, metal forming machines, and multi-axis systems in manufacturing plants. For example, a model HCS03.1E -rated around 100 A would handle a sizable servo motor in a machine tool or extrusion line.

HCS04 Features: The IndraDrive C HCS04 series represents some of the most powerful single-axis converters in the market. These units can provide continuous currents well above 600 A, with peak currents on the order of 1000 A for short durations​. Depending on configuration, an HCS04 drive can control motors in the several-hundred-kilowatt class – suitable for very large extruders, paper mill rollers, or heavy press drives. Many HCS04 models include robust internal brake choppers and resistor banks to absorb regenerative energy. (For instance, one HCS04 unit includes a 400 kW braking module to safely dissipate energy when decelerating massive loads​.) The larger HCS04 IndraDrive C units often require higher capacity cooling and may come in bigger form factors (weighing over 200 kg for the largest models​), but they maintain the all-in-one convenience and are widely used in industries like pulp & paper, steel, and automotive due to their proven performance​.

Both HCS03 and HCS04 drives carry international approvals (CE, cULus, etc.) and safety functions, giving engineers and plant managers confidence in deploying them globally​. With these high-power IndraDrive C units, Bosch Rexroth has effectively covered the entire spectrum of servo drive needs under a unified platform. This means easier maintenance and commonality for companies that might use smaller IndraDrive Cs on one process and large HCS04 drives on another – the programming tools and many options remain consistent across the range.
